FL'USI-LTANK APPARATUS. f

Application filed December 9, 195. Serial No. 74,287.. Y

T0 all whom t 'may concern.' f

Be it known that I, `EDMUND BEAcH, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Flush-Tank Apparatus, of which the following is a specification.

This invention relates to flush tanks for water closets and its object is to provide a flushing apparatus whose construction shall be as simple as possible and whose operation shall also be reliable and require little attention and the use of only inexpensive parts to keep it in order.

In my apparatus the water tank is movable vertically and controls the water inflow,-when depressed by the weight of the water therein, shutting off the inflow, but when the water has been withdrawn and the tank is thereupon elevated by suitable means, allowing such inflow. This isnot in itself new; but it is new to introduce the water through an upwardly open valve-seat adapted to be yclosed by a downwardly moved valve which is` seated by the tank as it is iilled,thus simplifying the mechanism and rendering the closing actioncertain,y and this constitutes one feature of the present invention. Another 'feature `consists in placing the tank in a water-tight casing which has a discharge outlet and providing for overflow of the tank into the casing; the overflow may be by way of an outlet formed as a standpipe which surrounds the inlet pipe (having the mentioned valve-seat), and in that case the standpipe will aiford the partV of the tank structure to which the means 7 for opening and closing the valve is connected.

The discharge of the tank may be eected in any way, as by providing a service outlet therein normally closed by a valve. This valve may bemanually operated; or I may construct the entire apparatus so that automatic intermittent flushing may be carried onv by using means to evacuate the tank including a valve device, asa float valve, for this service outlet that is movable up and down in some part of the apparatus with respect to which the tank moves vertically and which valve device has its own downward range of movement short of that of the tank,

this constituting a third feature `of the invention.

In the drawing,

Fig. l is a vertical sectional view of a .flushing apparatus embodying the Y invenn tion;

Fig. 2 is a plan thereof; and

Figs. 3 and 4 are longitudinal and transverse sectional views, respectively, of the mentioned automatic type of the apparatus.

Let a designate a part of fixed structure, here in the form of a casing open only at the top and provided with a removable cover a', and also water-tight. Another part of such fixed structure is a water-supply pipe b extending up through the bottom of the casing and suitably secured tothe same and having an upwardlycopening valve-seat c, the latter being in the present example actually formed in an extension d of the said pipe which is bent downward to form a discharge leg and has over the valve-seat an externally threaded opening d normally closed by a cap e screwed thereon; the extensiond may be screwed onto the pipe b and it may havel a spider al below the valveseat. l

`The casing contains a water tank f movable up and down therein and when empty held at a suitable elevation by any suitable means, as plate-springs g secured on the bottom of the casing. The tank has a standpipe h which loosely embraces the .pipe b vand reaches suitably above that level, indicated v`at! m in Fig. 1, which is the normal filling A,

level of the tank; said standpipe affordsv in effect a safety outlet, i. e., it constitutes means, usual in` flushing apparatus, foraffording overflow, the water which flows over the top of and down through the standpipe .l

inthe present case being received bythe cas` ing from whence it is discharged through the pipe z' suitably secured tothe bottom of the casing and being in the present example the mentioned discharge outlet.

The valve for closing the valve-seat cf is indicated at It is in the present case a simple spindle which penetrates and is guided by the cap e and also by the spider; its

actual seating portion is preferably a rubber or leather washer j. Ifalls this valve is moved downwardly `thereby and closes the valve-seatand when the tank rises it releases the valve, the downward movement in the present case being accomplished by a lever la which is fulcrumed on an arm e of the cap and has a pivotal connection c with the valve and a link Z which is pivoted to the lever and, depending therefrom, extends freely through a hole m When the tank i in a projecting lug of a collar msecured to the standpipe, the lower end of the link being bent off.

A short length of pipe at n suitablysecured in the bottom of the tank f and preterably projecting' into the pipe forms the service outlet of the tank. 0 is a ioat valve for closing the service outlet, ythe same being of well known type and including an upwardly projecting stem `0 connected with a lifting link p which is in. turn connected with a manually'operated lever g fulcrumed in va 'part of the iixed structure, as casing a,

"the connection between o and p being such that when the valve has been lifted by p clear of its seat Ait may be by iieatation movedupwardly independently of p, vreturning to its seat on the evacuation of the tank.

In Figs. Sand @the automatic intermittent operation fis due to the following construction :V yThe Yfloat valve ,g1 controlling vthe service outlethas its stem Q 'slidable ver'- tically in an arm 'r secured 'to apart of the liked structure,.as'casing a.; and the bento-ff end Q of-saidstem is yadapted .to limit the downward movement ot the valve short 'of Ythat ot thetankwhen, in being iilled, it

descends. v

In Figs. l and 2the operation is as tollows Whenthe-means 0 p g is operated to liftthe valve 0 from its seat the tank will be evacuated andthe loadwof the water being removed it will rise, permitting the 'pressure ofthe water in pipe 5to li'ftjva'lve'l j and the wateifto dow `intoi the tank. Thefmeans o pgbeifng'release'd lso that o ret-urns to its seat, the tank againy fills and [under the weight of 4the water vdescends vand so closes v'alvey'. uw

Inv Figs. 3 and 4, when the tank .in being v.filled and consequently descending reaches a certain level the rdownward movement Vof i the Valve guiar-.wiens cheeked by as bentf ters Patent is off end-fg, which lopens the valve and initiates the evacuation of the tank, the Valve remaining floating 'and open until evacuation is coinplete.` In the consequent rise of the tank valvefj, vwhich `was previously closed by the downward pressure of the tank, n ow opens andallowsfthe waterto 4flow in and, upon yvalve g assuming its seat,'to refill 'they tank,Y resulting Iin the tank again descending to bring abouta repetition of the operation. y, f Y y I-Iaving thus fully -'described mymvention what I claim and' desire to secure by Letl.y In lcombination ytired:str'iucture. includl `ing an upsta'nding water-supply pipe, a G0v tank movable-up and dwnfand havlng a service outlet, means to"co1trol the flow 'of water from the outlet, downwardly yielding means arranged fon said st'r'i'icture and @carry- 'or' the tank tothe lever.
